<?php
require_once "fullshop.php";
class ReflectionUtil {
  static function getMethodSource( ReflectionMethod $method ) {
    $path = $method->getFileName();
    $lines = @file( $path );
    $from = $method->getStartLine();
    $to   = $method->getEndLine();
    $len  = $to-$from+1;
    return implode( array_slice( $lines, $from-1, $len+9 ));
  }
}

//$class = new ReflectionClass( 'CdProduct' );
//$method = $class->getMethod( 'getSummaryLine' );
$class = new ReflectionClass('shopProduct');
$method = $class->getMethod('__construct');
print ReflectionUtil::getMethodSource( $method );
$properties=$class->getProperties('__construct');
foreach ($properties as $property){
  echo '<br>property: '.$property;
}
?>

I want to echo all the properties of the method __construct in the shopProduct class
PHP OOP does not work that way.  "Properties" are the data elements of the object (not limited to any one method) and they are visible according to their definition as public, protected, or private.
http://php.net/manual/en/language.oop5.properties.php
http://php.net/manual/en/language.oop5.visibility.php

Within a method, there may be local variables.

<?php // demo/temp_rgb192.php
error_reporting(E_ALL);
echo '<pre>';

// SEE http://www.experts-exchange.com/Programming/Languages/Scripting/PHP/Q_28421888.html

Class Rgb192
{
    protected $myVar = 3;
    public function __construct($x)
    {
        $this->x = $x;
    }
    public function showMe()
    {
        $y = 5;
        return get_defined_vars();
    }
}

$obj = new RGB192('ABC');

// FINDS THE LOCAL VARIABLES INSIDE THE SHOWME() METHOD
var_dump($obj->showme());

// FINDS ALL OF THE PROPERTIES OF THE OBJECT - DOES NOT INCLUDE LOCAL VARS
var_dump($obj);

For a deeper understanding of how to produce meta-data about your classes, you may want to make a tour-de-force study of this, setting up code examples to demonstrate the various methods:

So object is properties and methods
Reflection is class

Yes, but there is a lot to learn about Reflection.  This seems to be a good starting point:
